t I WIRE LINE AND ROD COUPLING.

Application filed March 10, 1923. Serial No. 624,193.

of Oklahoma, have invented new and useful Improvements in Wire Line and Rod Couplings, of which the following is a spec1fica- This invention relates to coupling devices and has for its object the provision of a novel device for coupling together lengths of line wire cables, rods or the like, and for repairing broken cables and rods such as are used in pumping machinery or drilling rigs in connection with oil or other wells,

the device being however capable of use in other capacities-in other arts as no restriction as to employment is made.

An important object is the provision of a deviceof this character which is provided with means for positively gripping the lengths of cable, rod or the like so as to prevent slipping at any time even under the most severe strains.

An additional object is the provision of a device of this character which will be simple and inexpensive to manufacture, easy to assemble, ositive in operation, efiicient and durable in service and a general improvement in the art;

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the device,

Figure 2 is an elevation at right angles to Fi re 1,

- igure 3 is a longitudinal section,

Figure 4 is a cross section through the center,

Figure 5 is a cross section near one end,

Figure 6 is a perspective view of one meml 'gure 7 I wed and i F1 re 8 is a' perspective view of one of the s ips.

Referring more particularly to thadrawingsl have shown my device as comprising a pair of similar body members 10 which may be described as mating in reversed reis a perspective view of the lation and each of which includes a preferably taperedend portion 11 formed with a tapered bore 12. At substantially its center each body member is cut away to define a recess 13 and an extension 14 which defines a shoulder 15. It should be stated that the bore 12 extends throughout the body member, that is even through the extension 14. It will be observed that theshape of the recess 13 and extension 14 is such that when the two body members 10 are placed together in reversed relation, the extension 14 of each fits within the, recess 13 of the other, the shoulders 15 abuttingly engaging as shown in Figure 2. Onebody member is formed with a rectangular opening 16 intersecting the recess'13 while the other body member is flprmed with a hole 17 registering therewit It is intended that the sections A and B of the rod,-fc able or the like to be connected be placedifwithin the bores 12, and to effect,

a proper holding action thereon, I provide within each bore a pair, or more, of slips 18 which are tapered throughout their length for wedging'engagement within the bores, and which have their inner surfaces serrated as indicated at 19 for exerting a biting action on the rods or cables. I

The numeral 20 represents a wedge block which is inserted through the opening 16and-- which is wedge shaped for engagement with the inner ends of the rods or cables for the purpose of forcing them outwardlyin gripped relation by the slips within the bores. The outer end of this wedging block is provided with-a head 21 which prevents it from slipping too far into the device and passin through the wedge block is a bolt 22 which passes through the hole 17 and which carries an ordinary nut 23.

In assemblin the device, the sections A and B of the rod or the like are placed with in the bores 12 and the slips 18 are inserted into the bores in embracing relation to the sections, prior to the connection oi the body members 10 with each other. The body members are then placed together with their extensions 14 fitting within the recesses-13, the wedge block 20v is forced through the opening 16 the bolt 22 is the wedge block and hole 1 and the nut 23 is applied and screwed down. Initially the inner ends of the rod or cable sections A and B. will be comparatively closetogether so that when the wedge block 20 is inserted, the inclined sides thereof will engage the passed through and t at the bores are also tapered, it

is obvious that-the slipswill firmly engage the sections and prevent slipping thereof outwardly while the wedge member prevents the sections from moving inwardly. The bolt 22 also serves to hold the two body members together so that dislocation of any" of the parts will be absolutely prevented.

Fromv the foregoing description and a study'ofthe drawings it will be apparent that I have thus provided a simply constructed, inexpensive and yet most highly efiicient co'nnector of the class described which will have the maximum strength and durability and which is not likely to get out of order.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or, the scope of the -subjoined claims. Having thus described myinvention 1 claim:

within the recess of the other, the rod sec-' tions being ada ted to be inserted within said'bores, a we ge block insertable through said opening and engaging the inner ends of the rod sections for forcing them outwardly, and a bolt her and t clamg ilng said members together. I

' 2. eans for connecting rod sectionscom prising apair of. similar body members each formed with a tapered bore and each having one end recessed to define an extension, one member being formed with a transverse opening leading into the recess and the other beingv formed with a hole leading into'the recess and designed to register with said opening when said members are assembled Wijth the extension of each fitting with in the-recess of the other, the rod sections being adapted to be inserted within said bores, and bolt operated wedging means for engaging the inner ends of the sections and forcirig them outwardly.

3. cans for connecting rod sections com: prising a pair of similar body members detachably connected and each formed with a tapered bore, one member having an opening therein and the other being formed with a hole registerin with said opening, the rod sections being a apted to be inserted within said bores, split tapered slits within said ores and engaging said rod sections, a wedge member extending through said open-' ing, and engaging the adjacent end of said rod sections, and a bolt passing through the wedge member and through said hole and equipped with an adjusting nut whereby to move the wedge member longitudinally to force the said rod sections outwardly.

In testimony whereof I aflix mysignature.
